Description

The gas slag isolation integral that is used for coal mine down-hole drilling faces picking device
Technical field
The utility model relates to coal-bed gas extraction technical field, and particularly a kind of gas slag isolation integral that is used for coal mine down-hole drilling faces picking device.
Background technology
Execute when boring in high fiery colliery down-hole, occur gas often and spray security incidents such as boring, transfinite.Along with the continuous increase of mine quantity, it is particularly important that gas control seems, the means that extraction boring is administered as the zone seem more and more important.And much mines are in the drilling construction process at present, and it is serious to cross coal seam spray brill, cause gas " two high " phenomenon more and more serious, greatly threatening the safety in production of down-hole.For this reason, Chongqing pine algal coal electricity Co., Ltd once applied for the utility model patent of " a kind of colliery is with gas dust catcher " on April 15th, 2011, and its application number is 201120111827.1, and this application has been authorized patent right on October 5th, 2011.This catcher is mainly caught the sleeve and the gas dust seizure case of part by constituting dust; And the current divider box composition that constitutes gas slag separating part, its middle sleeve stretches in the boring hole, and the gas dust is caught case and current divider box is located at outside the hole; The gas dust is caught case and is connected with dustproof spraying water pipe; The Device in Gas outlet of current divider box is communicated with the gas exhaust pipe with subnormal ambient, and the gas gaseous mixture that contains dust during boring gets into the gas dust from sleeve and catches case, and dust is through getting into current divider box with gas behind the spraying humidification under suction function; The dust gravitate sinks from the slag-drip opening discharge of current divider box naturally behind the humidification; Water is discharged from outfall, and gas gets into the gas exhaust pipe and is collected under suction function, thereby the zone of realizing coal mine down-hole drilling is administered.When this catcher had successfully solved construction drill, the problem that the return side dust concentration is big had effectively reduced the number of times of gas exceeding limit when construction drill is worn the coal seam.But, this catcher need overcoat one water pocket or air bag to make itself and borehole wall form sealing because stretching into the sleeve of boring; In boring procedure, drilling rod drives sleeve easily and rotates or compression sleeve, causes water pocket or air bag to damage in early days; Make between sleeve and the hole wall and form the slit; Device in Gas and dust spill from the slit between sleeve and the hole wall easily, particularly when the boring spray orifice is serious, and Device in Gas and dust even gush out from the slit between sleeve and the hole wall; Thereby cause gas exceeding limit or dust to exceed standard, bore the personnel component security threat executing.
Summary of the invention
The purpose of the utility model is exactly the deficiency to prior art, provides the gas slag isolation integral that is used for coal mine down-hole drilling that a kind of no gas of holing leaks potential safety hazard, long service life in early days to face picking device.
For realizing above-mentioned purpose, the utility model adopts following technical scheme.
A kind of gas slag isolation integral that is used for coal mine down-hole drilling faces picking device; Comprise dust gas seizure tube, an aqueous vapor slag separator box, dust gas is caught tube and is provided with slag-drip opening and atomizing inlet hole, and aqueous vapor slag separator box is provided with gas recovery holes, slag notch and dewatering outlet; Said dust gas is caught tube and is comprised that a part of length stretches into the inner core in the boring; The outer wall of inner core forms with the boring inwall through sealing device and is tightly connected, and the outer end of inner core is through the coaxial bearing that is provided with in the bearing support rotary head that is rotationally connected, rotary head be provided with one can pass drilling rod through hole; The pore coaxial line of through hole and inner core, through-hole diameter is less than the pore diameter of inner core; Said slag-drip opening and atomizing inlet hole are located on the inner core.
